Today is my 190th day on MFP and Im officially down 65lbs. I workout for 30min/5 days per week. (elliptical/dumbbells)
Counting my calories and tracking on MFP has been the #1 contributor to my weight loss. Eating a deficit - thats it! No "diet", no depriving myself of foods I love, no expensive weight loss system.
If you are discouraged and having hard time with success: Drink TONS of water and make sure you are eating ENOUGH! MFP already calculates a deficit for you when giving you a daily calorie allowance - stick to it! I find that if I dont eat ENOUGH, my weight doesn't change.
